In the transition from KDE 3 to KDE 4, a new file manager, Dolphin, was often discussed and now officially moved to the base part of KDE. "I just stumbled over this message saying that the file manager Dolphin is now part of kdebase (of KDE 4): 'Moving Dolphin to kdebase, as discussed with Peter and others. The big plan is: Dolphin will become the default file manager (kicker buttons and file:/ links bring it up).' The question remains what now happens with Konqueror - keep in mind that one of the goals of KDE 4 was to only keep one app for each task inside the base packages. But with Dolphin as the potentially new file manager and Webkit as the new browser we may see Konqueror vanish."
